HMT-SF micro

Cutting machine for micro parts

Quick overview

• Combined cutting and chamfer grinding
• Diameter: Ø 0.68–4 mm
• Automated

The HMT-SF micro is a fully automated system developed for cutting and chamfering very small round bars made from a wide range of materials, including carbide, HSS and ceramics. Convenient external loading allows production to continue without downtime.

Technical specifications

Loading

1. Load blanks into the external magazine manually or automatically.
2. Enter the desired length and quantity on the touchscreen.
3. Press Start.
4. The external magazine moves into the machine, places the bars in the internal magazine and returns to its home position. Once it has returned, it can be loaded again while production continues.

Input check

The rods are automatically transferred from the internal magazine to the prism, positioned, clamped with a collet and cut. Before positioning for cutting, the rod length and diameter are checked.

Cutting

• The integrated sharpening unit can automatically sharpen the cutting wheel during the cutting process.
• The cutting wheel is checked by an automatic diameter control.

Parts suction

The cut parts are extracted from the clamping unit to the removal station through extraction tubes optimised for different part sizes.

Parts sorting

After cutting, the parts are transported to the removal station and sorted. Good parts and off-cuts are separated and collected in different containers.

Options

• Additional chamfer grinding station for processing both ends
• Machine data acquisition (MDA)
• Oil mist extraction
• Compact fire protection system
• Coolant filtering system
• Coolant return pump tank
